东吴汽车黄细里团队·2025-12-07 09:59Core Viewpoint - The demand for liquid cooling and robotics driven by AI is experiencing an explosive growth, initiating a new growth curve for the automotive parts industry. AI is continuously upgrading computing infrastructure and smart terminals, leading to the necessity of liquid cooling systems in high-power density scenarios, while robotics is transitioning from 0-1 to 1-10. This synergy between liquid cooling, robotics, and automotive parts is reshaping the business boundaries and growth trajectories of the automotive parts industry [2][8]. Investment Highlights - The automotive parts industry, equipped with technological synergies, system integration, cost reduction capabilities, and global capabilities, is set to benefit from the AI-driven wave. Automotive manufacturers and parts companies are expanding their business boundaries to achieve "homogeneous manufacturing + scenario collaboration." The collaboration between automotive companies and parts manufacturers will transfer the brain capabilities of intelligent driving to embodied intelligence, with companies like Tesla, Xiaopeng, and Xiaomi migrating their models, data, computing power, and supply chain systems to embodied intelligence [3][8]. Investment Recommendations - Liquid cooling is entering a phase of large-scale penetration and high prosperity realization. With the stabilization of Tesla's robot V3, the sector is moving into the 1-10 phase, focusing on certainty and supply chains with global capabilities. Recommended companies in the robotics sector include Top Group, Zhongding, Xiaopeng Motors, Junsheng Electronics, Shuanghuan Transmission, Aikodi, Xingyuan Zhuomai, and Xusheng Group. For the liquid cooling sector, recommended companies include Top Group, Zhongding, Yinlun, and Feilong [4][8]. Robotics Development - The Optimus V3 is expected to be finalized soon, marking the transition of T-chain robots into the 1-10 phase. Tesla has established a dual-driven approach of hardware architecture convergence and large model/training foundation, with plans to initiate a million-unit production line by the end of the year. The focus will be on the dexterous hand and brain capabilities, with significant advancements in technology and design expected [13][40]. Market Trends - The humanoid robot sector is anticipated to mirror the growth trajectory of the new energy vehicle sector from 2010 to 2014, currently in the pre-investment stage. The penetration rate of new energy vehicles is expected to rise significantly, with the humanoid robot sector beginning to see substantial order changes and early application scenarios coming to fruition [27][31]. Supply Chain Dynamics - The domestic robotics industry is characterized by a diverse landscape of technology giants, automotive manufacturers, startups, and academic institutions. The focus is shifting from factory training to small-scale external sales, driven by educational and industrial pilot projects [41][45]. Sensor Technology - Robotics sensors are categorized into four types: force sensors, visual sensors, position sensors, and tactile sensors. The six-dimensional force sensor is the most valuable, while visual sensors are primarily composed of laser radar and RGB cameras. The demand for these sensors is expected to grow significantly as the robotics industry advances [71][73]. Cost Reduction Strategies - Domestic manufacturers are expected to accelerate cost reduction through the production of precision gears and bearings, which can be used interchangeably with robot reducer production equipment. The price of domestic harmonic reducers is significantly lower than that of overseas products, indicating a strong potential for domestic substitution [65][66].
